Implement control measures when there is one defoliated spot per ______ of buffalograss.

• A. square yard
• B. square foot
• C. acre
• D. square meter

Answer: (A)

In turf pest management, decisions about when to control pests are guided by scouting thresholds—the level of damage that justifies treating. For buffalograss, a practical and reliable sampling unit is a small, standardized area that you can easily survey in the field. Observing one defoliated spot within a square yard provides a clear, action-worthy signal of pest pressure that is neither too sensitive nor too lax. This density reflects early-to-moderate damage typical of localized infestations, prompting timely control before the problem spreads, while avoiding unnecessary treatments for minor or isolated damage. Using a square yard aligns with common turf management practices in the United States, where field measurements and thresholds are routinely expressed in imperial units. A unit like a square meter or a square foot either introduces scale that’s too coarse or too granular for practical scouting in buffalograss patches, and per acre would obscure localized damage early enough to intervene. So one defoliated spot per square yard is the best, most actionable standard.
